  Hello everyone,
  
  I am dealing with convergence issue in Static structural problem. I have two types of non - linearity - contacts and large deflection. I will try to describe my model with attached pictures. The main part of my model is metal sheet of dimension 6000×150×8 mm (I am using symetry on a long edge)
  
  I am using two frictionless and two no separation contacts,
  
  The expected deformation can be seen on this picture, howewer, I can not push the metal sheet about the full deformation 500 mm. It always stops converging, when the metal sheet lay fully on the supports.
  
  If anyone could give me some recomendation with solver settings, I would be really greatful.
  
  Thank you
  
  Best regards
